Keisha and Jamaal take the same standard math test. The ratio of their scores is 4 to 5. The difference in their scores is 15. What are their scores?

Keisha's score is 60

Jamaal's score is 75

Step-by-step explanation:

Take the ratio of 4:5 and turn it into a fraction: 4/5

Then take the fraction and multiply each value by the difference in their scores.

So 4x15=60 and 5x15=75

This checks out as 60/75 comes out as 4/5, which is a 4:5 ratio and the difference between the two is 15
